Looking for Inertial Blending support in Unity.

I’m aware of of the Inertial Blend example built on “com.unity.animation”, but I don’t think DOTS is ready, and the code looks frustratingly unreadable to me.
I suppose it’s not possible to extend mecanim for that (or is it?).
Is there a third party plugin that’s comparable to mecanim or Animancer in core features, but easily extensible for custom transition?

Are you looking for a GameObject solution or an ECS solution? I have the latter.

I’m looking for a more “traditional” looking solution, because the whole ECS concept is too alien to me. I would like to try if comes with better facilities: visualizer, editor, etc, things Unity is still lacking (unless I missed something), so I don’t have to worry about the API.
